Solve the system of inequalities by graphing: \( y \ge \frac{3}{4}x - 2 \) and \( y < -\frac{1}{3}x + 2 \).

Back

Graph the two lines and shade the appropriate regions.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

Front

What does it mean if a line is dashed in a graph of inequalities?

Back

The line is not included in the solution set (for \( < \) or \( > \)).
